There are tons of Halo fan films. Tons. Here's another, but what sets it apart is how the filmmakers were able to squeeze blood from stones.
Shot for only US$850, Halo: Faith is a short film that was born out of an "simple conversation" between filmmakers back in Oct. 2010.
The effects aren't as good as in a big Halo production, but big Hollywood productions cost a bajillion times more than this.
And I quite like the narrator.
